This project presents the design of an electrical power generation system, which takes advantage of a person’s movement when exercising on a static bicycle. This system is implemented in a gym located in Suchiapa, Chiapas. The analysis is carried out of three categories of people: high performance athlete, occasional athlete and sedentary person, to evaluate the calories consumed per day and exercise time on static bicycle. This information provides an estimate of the energy generated in one day, to compare the receipt of power consumption of CFE before and after the system. The static bicycle is mechanically attached to a generator by means of a support, followed by a diode allowing the passage of the electric current with characteristics similar to a switch, which is connected to a voltage regulator that maintains a constant voltage level. The regulator is coupled to the electric accumulator and an inverter. The latter is in charge of converting the direct current input voltage and alternating current output. By implementing the mechanism with nine static electric bicycles, an energy saving of 17.57 % is obtained.
